If you configure multiple IP tunnels between two IP nodes, and enable ip_strict_dst_multihoming or other IP filters, packet loss might result.
Workaround: Choose one of the following workarounds.
First, configure a single tunnel between the two IP nodes. Add addresses to the tunnel by using the ifconfig command with the addif option.
Do not enable ip_strict_dst_multihoming on tunnels between two IP nodes.
